Gold and Silver Plating Basics : Products Finishing

Most plating of gold and its alloys is carried out from solutions containing gold as a soluble cyanide complex. Gold reacts with alkali cyanides to form either monovalent {MAu(CN)2} or trivalent {MAu(CN)4} complexes, wherein M is an alkali metal or, in some cases, ammonium ion.
